篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了支护宝api接口开发相关的知识,希望对你有一定的参考价值。
支付宝的接口和微信的DEMO和文档真心太难看懂了,乱七八糟,都不知道去哪里找自己要的东西,最近几天我们公司需要做类似的开发,我作为先锋,率先解决Java集成支付宝支付和微信支付接口工作。
我们的工作环境:JSP网站+支付接口,目前工作的支付宝接口为20160912,微信为V3版本,如遇到版本升级,请联系相关机构的客户服务人员升级。
本文介绍JSP+支付宝接口,本文非原创。
新手注意:
1、本文使用的接口地址和参数为沙箱的地址,无论你在使用沙箱或者正式地址,务必核实使用接口地址和参数,不要想当然。
2、本文使用JAR包:
alipay-sdk-java20160912220103.jar
commons-codec-1.6.jar
commons-httpclient-3.0.1.jar
commons-logging-1.1.1.jar
fastjson-1.2.7.jar
json-lib-2.2.3-jdk13.jar
json.jar
jsp-api.jar
servlet-api.jar
说明:
alipay-sdk-java 是官方支付SDK,请到官方下载,本文使用版本20160912
